To determine which number line best represents the number of weeks it will take Alma to read at least 28 books, we first need to calculate how many weeks will be required based on her reading rate.
Alma reads 2 books per week. To find the number of weeks (let's call it \( w \)) needed to read at least 28 books, we can set up the equation:
\[
2w \geq 28
\]
Now, we can solve for \( w \):
1. Divide both sides by 2:
\[
w \geq 14
\]
This means it will take Alma at least 14 weeks to read at least 28 books.
In terms of the number line representation:
- The number line should start at 14 and extend indefinitely to the right (indicating that any number of weeks greater than or equal to 14 is acceptable).
Among the options given (A, B, C, D), you should look for a number line that has a point or mark at 14 and an arrow (or shading) extending to the right.
Without seeing the specific options, I cannot definitively tell you which one is correct, but ensure you look for a line that depicts \( w \geq 14 \).
